An event-driven system, method and computer program product are provided to selectively generate events in response to receipt of data elements. The event-driven system includes processing circuitry configured to identify, in response to receipt of one or more data elements, an event that is impacted by the one or more data elements. The processing circuitry is also configured to determine whether at least a threshold number of consumers are currently listening for the event. In an instance in which at least a threshold number of consumers are currently listening for the event, the processing circuitry is configured to perform one or more computations based upon the one or more data elements to generate the event. Otherwise, however, the processing circuitry is configured to at least defer the one or more computations that would be performed upon the one or more data elements to generate the event.
